You're right that heat kills the big battery. (aka LiIon traction battery).
I've never seen data showing that cold kills the small battery (aka lead-acid 12V battery). Heat definitely kills lead-acid batteries. That is well documented.
On ICEs, cold temperature puts heavier demand on lead-acid batteries, so people with ICEs see their cars fail to start in cold weather, but that's for another forum.
